Application filed March 28,1899. Serial No. 710,799. (No model.)

T0 to whom rt may concern.-

Be it known that we, DAVID K. WILHELM and SAMUEL A. LOUDER,citizens ofthe United States, residing at Oresson, in the county of Cambria andState of Pennsylvania, have invented certain new and useful Improvementsin \Vrenches; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which itappertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in wrenches, andparticularly to a sliding-jaw wrench in which the shank portion of thejaw slides in a dovetailed recess in the fixed part of the wrench,having the integral jaw therewith, meansbeing provided to securely holdthe sliding jaw in an adjusted position.

More specifically, the present invention resides in the provision of adouble-ended sliding-j aw pipe and nut wrench in which the shank of thesliding jaw at each end is arrowshaped in longitudinal section anddesigned to slide in a similar-shaped recess in the body of the wrench,suitable set-screws being provided to hold the sliding jaws in their adjusted positions.

To these ends and to such others as the invention may pertain the sameconsists, further, in the novel construction, combination, andadaptation of parts, which will be hereinafter more fully described andthen specifically defined in the appended claim.

Our invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form apart of thisapplication, and in which drawings similar letters of reference indicatelike parts throughout the several views, in which- Figure 1 isaperspective view of our wrench complete. Fig. 2 is a side elevationshowing the shank portion of the sliding jaw and showing the recess inwhich said jaw slides. Fig. 3 is a horizontal section through the jaw,showing the manner of holding the sliding jaw in an adjusted position.

Reference now being had to the details of the drawings by letter, Adesignates the handle of the wrench, which is made, preferably, of theshape illustrated in the drawings and has an integral jaw A at one end,forming a part of the sliding pipe-wrench, and a corresponding integraljaw A at the opposite end, forming a part of the sliding nut-wrench. Atone end of said wrench the 'body portion is cut away at right angles tothe face of the stationary jaw of the nut-wrench, and said body portionadjacent to the cut-away portion is recessed in the shape illustrated toreceive the shank portion B, which is integral with the sliding jaw 13.The opposite end of the said handle is provided with a similar slidingjaw to that above described, and each of said sliding jaws is held in anadjusted position by means of the tightening-screw O, the shank portionof which is pivoted and works in a threaded aperture 0 in the head ofthe wrench, and by tightening said screw its inner end is brought intocontact with the face of the shank portion of the sliding jaw and bearswith sufficient pressure against said jaw to hold it in 'a fixedposition.

Having thus described our invention, what we claim to be new, and desireto secure by Letters-Patent, is

As an improved article of manufacture, a sliding-jaw wrench, consistingof the shank portion having a stationary head, the out line of which ison the arc of a circle, a flatshouldered portioh of said headterminating in a right-angled wall havinga series of teeth, combinedwith a sliding jaw having a shank portion with laterally projectingwings, adapted to slide on shoulders formed in the walls of a recess inthe stationary jaw, anda tightenipgscrew designed to bear against theside of the shank of the sliding jaw, as shown and described.

In testimony whereof we affix our sigmatures in presence of twowitnesses.
